  • Method for inhibiting occurrence of pyrolysis deposit in pyrolysis gasification system, and pyrolysis gasification system
    Patent number: 10377952
    Abstract: This method for inhibiting the occurrence of a pyrolysis deposit in a pyrolysis gasification system includes: gasifying biomass (S2) through pyrolysis in a pyrolysis gasification furnace (5); separating, in a solid-gas separation unit (7), a pyrolysis gas (G1) and a carbide (C) continuously formed through pyrolysis of the biomass (S2); feeding an oxygen-containing gas (G3) to the separated pyrolysis gas (G1); and introducing the pyrolysis gas (G1) together with the oxygen-containing gas (G3) to a combustion furnace (6) through a pipe (9) which constitutes a pyrolysis gas line (8).
    Type: Grant
    Filed: July 11, 2013
    Date of Patent: August 13, 2019
    Assignee: MITSUBISHI HEAVY INDUSTRIES ENVIRONMENTAL & CHEMICAL ENGINEERING CO., LTD.
    Inventors: Yuuki Endou, Takehiro Kitta, Kazuaki Kakurata, Junichiro Abe
